            <h2 id="概述"><a href="#概述" class="headerlink" title="概述"></a>概述</h2>
            <p>某些项目使用 jenkins 做自动构建，一份代码可能会部署到多个环境，如：正式环境、预发布环境、测试环境、本地开发环境。运维不可能每次都去手动改变我们的代码，所以，就需要前端可以针对不同的部署环境进行构建配置。对于多人维护的项目应该有一个可以统一的本地开发环境，不需要每个人再去配置。</p>
            <h2 id="依赖支持"><a href="#依赖支持" class="headerlink" title="依赖支持"></a>依赖支持</h2>
            <p>本方案使用的是 <a target="_blank" rel="noopener" href="https://www.npmjs.com/package/gulp-preprocess">gulp-preprocess</a> 插件，该插件可以构建一个可配置的上下文供我们在构建时使用。</p>
            <p>同时使用 <a target="_blank" rel="noopener" href="https://www.npmjs.com/package/gulp-connect">gulp-connect</a> 支持本地开发的服务。</p>
